The presence of water lowers the solidus temperature of rocks at a given pressure. It drastically changes the melting temperature by a vast amount.
The presence of water can lower the melting temperature of a rock by facilitating the movement of ions and promoting the process of melting. Water reduces the viscosity of molten rock, making it easier for the rock to melt at lower temperatures.
Water reduces the melting point of rock.
The presence of water can lower the melting temperature of a rock by facilitating the transfer of heat and promoting the formation of liquid magma. Water can act as a flux, which helps to break chemical bonds in the rock and decrease its melting point. This process is commonly seen in the formation of magmas in subduction zones and other tectonically active regions.
Magma consists of molten rocks and metals. The composition can vary based on presence of water, metals with different melting points, and such.
the hotter the water the faster the ice will melt
Yes. The presence of water can significantly reduce the melting temperature of rock. For example the presence of water and other volatiles in a subducting slab of oceanic crust that acts to significantly reduce the melting temperature of the mantle material above it leading to the formation of magma and the volcanism that is associated with subduction zones.
The melting and freezing points of water are primarily affected by external pressure and the presence of impurities. Increasing pressure raises both points, while adding impurities lowers them. Additionally, the purity of the water molecules and the surrounding environment's temperature also play a role.
As the water content of rocks increases, the melting point typically decreases. This is because the presence of water lowers the melting point of minerals in the rocks by acting as a flux that promotes melting. The addition of water creates a eutectic point where the rock will begin to melt at a lower temperature.
It doesn't. It does slow the melting of rock, but only because of the specific heat of water. (i.e. you've got to heat the water too.)

Adding salt to melting ice lowers the freezing point of water, causing the ice to melt at a lower temperature. This results in faster melting of the ice.
Water can lower the melting temperature of a mineral by acting as a flux or catalyzing agent, allowing atoms to move more freely and reducing the energy required for melting. This can lead to the formation of new minerals or phases at lower temperatures than would occur without water present.
